'S EPARATOR SYSTEM.

SPECIFICATION forming part of Iaette rs Fatent NO. 651,919, dated. June 19, 1900.

Application filed November 11, 1899. Serial No. 736,643. (No model.)

To all whom it may concern:

'Be it known thatL-DAvIs COCKRELL, a citizen of the United States, residing at Memphis, Shelby county, State of Tennessee, have invented certainnew and useful Improvements in Separator Systems, of which the following is a specification.

. My invention relates to an improvement in .stock. The lint is, however, Ytenaciously attached to the hull and ofiers considerable resistance to all efforts to separate them. It is therefore necessary to subject the hulls to repeated'treatment before the lint and branare entirely separated.

It is one objectof my invention to provide means of treating the hulls whereby they are subjected to; such vigorous and repeated op-. erations as maybenecessary to effect a OOIIl-f plete separation. i

It is the further object -to accomplishthis without the intervention of labor of anykind from the beginning. of the operation to the end and to accomplish this without damage to the building in which the plant is located or to surrounding buildings.

I accomplish the first two objects by the combination of a series of separators, chutes, grinding-mills, elevators,andfshakers so ar-, ranged that the hulls passed into the first separator are mechanically carried through the entire operation, and the third object by placing all high-speed and reciprocating machinery on a solid foundation onthe ground floor. I also accomplish the first of these objects by the novel combinationfof parts and construction of the beaters used.

In the drawings, Figure 1 is a sectional elevation on the lines 0 C and I) D of Fig. 4 looking in the direction of the arrows. Figs. 2 and 3 show enlarged end and side elevaparatively-slow speed and are placed on an upper floor.

11, 21, 31, 41, and 51 are corresponding grinding-mills, which run at a high rate of speed and'are on the ground-floor.

Two gravity-chutes 13 and 18 are connected 7 with each beater, as 10. The chute 13 con nects the opening through which all mate rial not beaten through the mesh of the screen is discharged with the corresponding grinding-mill 11, which mill in turn discharges into an elevator 14, which conveys the ground material to the hopper 27 of the next beater 2O. The chute 18jcarries off all lint and bran beat-en through the screen 15 of the heaters and discharges it, in common with that from the other heaters, through a chute 7 3 into a revolving screen 7 4, which separates the bran and the lint,the bran dropping througha'nd .thellint passing out the end to be baled.- Where the screen does not entirely separate the lint and bran, I provide a I shaking-table 76, throughwhich the bran is shaken, the lint passing onto the end to be baled, or if the end of the table 76 be so low that the shaker comes too near the ground an elevator 85 ,may be used to raise. it for baling.

While I have shown a revolving screen and a shaking-table and prefer to use them in that Way, I do not wish or intend to confine myself to theuse of thetwo at one time, for in some gradesfof materialeithe'r one will do the work. I such cases I prefer to use the shaking-table alone.

Referring now to details of construction, whileof course any beater may be used in the system I prefer to use. one, as shown, in which 10 is a box-casing having a door (not shown, but corresponding to 49,. and 5.9) to provide entrance to same, a perforated metal tened, and by means of these collars the pitch of the beater-blades, taken as a series, maybe regulated.

The screen, as shown in Figs. 2 and 3, is

composed of twopulleys {7-2, to which-a cyline der of perforated sheet metal or wire-netting is securely fastened, except that one section ishinged, as shown, and may be thrown open. to permit examination of the interior. 81 82rshow a means ofi-locliing the section 80 in place. The hub 71 is hollow, as shown, and the shaftil is'extended through same and journaled' outside. The beater further has a feed-hopper at one end, a discharge-hopper at the oppositeend thereof,and an opening inithe bottom of the casing 10, with a chute 1'8 leadingtherefrom, through which thematerial beaten through the screen falls.

The shaking-table consists of a frame '16,

Fig. 7, which has a screen 86 as a bottom. The shaking-tablev is suspended by twosets of short bars 77, loosely pivoted from crossbars 78, whichrest on posts 7 9. These posts and, in fact, the'entire shaking t'able are made separate from the other mechanism and are placed on a solid foundation onthe ground floor; I 84 is a short chute discharging into the shaker. e

'87 is a reciprocating rod to operate the shak-- ingftable'. Such meansof operation being in commoniuse, it is not/thought necessaryto further illustrateit. 7 1222, 850., are foundations for the mills' ll 21,18rc. 7 In operati'onhullsare fed into'the hopper 1'7 and throughiit into the first beater 10. There theblades 1 6, revolving rapidly, beat thelint'oif from the hulls and also beat out 3 any loose bran. This bran and a portion of thelint fallthrough the screen 15 into the chute 18, going thence to the shaking-table, where'the lint-and bran are separated. The

x hulls, with lint-attached, pass on through the '65 self to thatinumberof heaters or mills, and I" also wish it understood that, while I show in Fig ..5. a. diagrammatieplan. of. six .beaters ar rangedintwo rows of three each, saidrows being parallel to each other, it is neither my wishnor intention to limit myself to thisdouble row, since in some localities or situations it would. beimpossible. to secure space for two rows so'placed. I therefore desire that this specification be read to include asingle row. I have not separately illustrated a single row for the reason that three of the boaters of Fig. 5 sufliciently illustratethis single row. I am aware that many attempts have been made to solve this, problem, that much time and ingenuity have been expended, and that systems somewhat similar to mine have been I tried and are now in use These systems haye i many seriousdefects, on which; their inyen- 1' tors andmanyothers have-spent much time;- which in my system I have overcome. 1 am aware also that heaters and grinding-mills areold. I V

Therefore what I claim, and'desire tose'cu're l;by Letters Patent of the United" States, isv 1. In a separator system'fas a separator, ;the combination of a box-casing, open, at its ,lower side, having afeed-hopper at one end, :a discharge-opening at't'hejother, and an entrance door to permit access to a perforated 1 screen therein, 'of' the said perforated screen revolving therein said screen being open at 1 both ends, one open end'being so situated as to receive the discharge from thefeed-hop- .per and the other end "discharging into the 5 discharge-opening of the box-casing, thes'aid' screen also having one portion hinged to per l mit access to theinterior of sameand meansof fastening said hinged"p'ortion whenthe screen is in use, a central shafthaving aseries of beater-arms adjustably fastened thereto to permit variation of the pitch of the spiral formed by the arms, said'shaftjand arms revolving therein in opp'osite direction to the screen and" meansofrevolving the screen and the shaft therein in oppositedirections, substantially asset forth- 2. As aseparator syste'nn the combination .with a series of beaters each comprising a lbox-casin'g open at the bottom" having a 1 charginghopper at one end, a dischargeopening at the other end,a nda side door 7 permitting access to a perforated'screen therein, incombination with the said per forated screen adapted to berevolved therein, open ;at both ends and having one section hinged ,to permit access to theinterior thereof, and

lmean's of locking the section when thesci'een zis to be-p'ut in use, and a central shaft revolving in the-said screen in an opposite direction thereto,and having blades adjustably fastened thereto, of a series of grindingimills on a lower levelga series of gravity- ;chutes connecting the d ischargeends of the jzbeaterswi'th the corresponding mills, "a segries of elevators-connecting these mills wi'th ithe corresponding beater-hoppers, and a-se-- ries of gravity-chutes leading from the open In testimony whereof I have signed my name to this specification in the presence of 10 two subscribing Witnesses.
